Perhaps you should try some spelling variations:
der altertumer » des altertums
von nazianzus » von nazianz, _ nazianzus
zu gregor » 3 gregor, 20 gregor, 38 gregor
su gregor » sed gregor, 3 gregor, 20 gregor
_ gregor » _ gregory
reihe 4 » reihen 1

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: studien zur geschichte und kultur der altertumer : reihe 4, forschungen ((((zu gregor) OR (_ gregor))) OR (su gregor)) von nazianzus*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "studien zur geschichte und kultur der altertumer : reihe 4, forschungen ((((zu gregor) OR (_ gregor))) or (su gregor)) von nazianzus*".
